In both criminal and civil matters, investigators who specialize in documents look at every aspect of their composition and the information held within to determine facts about the case at hand. Those facts could be as simple as whether two handwritten notes were made by the same person or as complex as detecting counterfeit currency that manages to bluff the most advanced anti-counterfeiting measures.
Five Big Questions Answered
Forensic examiners look at a variety of document features to make key determinations investigators and attorneys can use to build a case. They do not analyze the information in the documents, but the documents themselves.
For example, if financial records need to be reconciled to find hidden money, that is the purview of a forensic accountant, not a document examiner. Similarly, assessing the quality of information in a piece of research or a testimonial to an event would require experts who can speak to that information. Essentially, forensic document examination specialists answer these questions about documents:
- Was a set of documents written by the same person?
- Was this document produced by the same machine as another?
- Has anyone made changes or alterations to the document after its creation?
- What inks or substances were used to make the markings? What was the writing instrument?
- Is the document a forgery?
These questions can have a huge impact on investigations in many areas. When it comes to financial fraud and disputes between individuals, it can show if any alterations were made to contracts or financial records that might point to an intentional deception on the part of one party or another. For investigations into other crimes, it can help determine if records provided for alibi or disclosures that indicate a party’s motive are accurate.
For civil cases outside of financial transactions and disputes around them, there are also a broad range of applications. For example, during a custody dispute, document examination could determine whether notes and communications one party accuses the other party of leaving are genuine. They can also be used to detect forgery if you suspect a contract was faked.
How It’s Done
When forensic professionals specializing in document analysis are assigned their duties by a client, it doesn’t matter if the client is a public entity like law enforcement or a private one like a corporate actor carrying out due diligence. The same scientific processes and professional ethics bind the examiner either way, and their duty is to uncover the truth about the document’s provenance and history, not to take sides in the dispute itself.
Since document examination techniques require a range of samples, the examiner may request additional materials like writing samples from the parties involved, or samples from the machine in question. Using these extra examples is the key to the technique, because the name of the game is close comparison. Machines that print documents have unique quirks that play out in their product, and by knowing how to look for the production characteristics caused by the machine, one can pinpoint whether two documents came from the same machine. The more points of comparison, the better the match, just like with fingerprint analysis.
Finding forgeries can be more difficult, especially when it comes to historic documents. Document examiners who apply forensic techniques to historic documents may not have other writing samples to look at or even other pieces of writing made with the same materials at the same time period. In those cases, they may need to turn to well-documented examples, like artifacts examined and published in detail in professional journals or those they can access with permissions at various archives. It can be a long process, and one that uses other testing techniques like various chemical and radiological dating techniques.
